The Discoverer M+S is Cooper’s Light Truck/SUV Studdable Winter / Snow tire developed for the drivers of SUVs , Jeeps, pickup trucks and crossovers looking for traditional wintertime traction on dry, wet and snow-covered roads. The Discoverer M+S is designed to provide enhanced grip on snow, slush and ice, and its foul-weather traction can be augmented with the installation of optional metallic studs.
Utilizing a winter-focused compound molded into a symmetric pattern, the Discoverer M+S features a sawtooth center rib to increase stability and aid acceleration and braking on clear roads. The four wide, circumferential grooves combine with large lateral notches to evacuate water from the contact patch and improve hydroplaning resistance, and the D Squared sipe technology increases sipe density and depth to optimize winter traction throughout the tire’s life. Cooper’s Snow Groove technology allows the tire to retain snow in the tread grooves, providing enhanced grip through snow-to-snow traction.
Internal construction of the Discoverer M+S consists of a two-ply, polyester casing. Two wide, high-strength steel belts are reinforced by a nylon cap ply to stabilize the tread and improve durability.
Discoverer M+S tires meet the industry’s severe snow service requirement and are branded with the three-peak mountain snowflake (3PMSF) symbol.
